Final Question on A4 Avant Help

[Mark Rosenkrantz]

Well, it might not turn on if the computer doesn't see one failed item.  High altitude combined with some lazy sensors and maybe some oxygenated fuel.... Or a partially plugged cat, etc.  A generic code reader isn't the best choice here.  Put that money towards a VAG-COM.

The it'll just be a matter of checking the wiring and likely replacing the sensor(s).  Depending on car history, there is likely more than one "lazy" sensor in the system, making it much more susceptible to poor running conditions.
